. SPECIFICATEON forming part of Letters Patent No. 329363, dated October 2'7, 1885.'

Application filed July :27, ISES.

To @ZZ whom it may concern/f Be it known that I, WILLIAM C. MrN'rLn, a citizen ofthe United States, residing at Liberty, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Rail-Joints, of which the following is aspeciiication, reference being had to the accompanying drawings.

My invention relates to improvements in rail-joints for connecting the meeting ends of the rails of a railway-track; and the novelty consists in the construct-ion, combination, and arrangement of the various parts for service, substantially as hereinafter fully set forth, and particularly pointed out in the claim.

The object of my invention is to provide a railway-j oint which shall be simple and strong in construction, efficient in operation, and capable of being applied to any ordinary rail.

In the drawings hereto annexed, Figure 1 is a side elevation of a railway-track having my invention applied thereto. Fig. 2 is a cross-section in the line x m of Fig. l, through one of the securing-bolts. Fig. 8 is a detail perspective view ofthe securing-plate. Figs. 4. and 5 are detail views of the securing-bolt and fastening-key. Y Y

Like letters of reference indicate like parts in all the figures of the drawings, referring to which A A designate the rails of a railway-track of ordinary construction, which meet and abut together at the point a, the web of each rail near the meeting ends thereof having one or more openings or apertures, a c', for the passage ofthe fastening or securing-bolts B B.

G C designate sh-plates secured between the head and foot of the meeting ends of the rails A and against the webs thereof, said plates being fitted on opposite sides of the rails and overlapping the ends thereof. The plate G has openings or perforations c of square form, and is adapted to receive the squared portion b of the bolt B, the openings therein registering with the openings in the web of the rail when the plate C is in position against the same.` The plate U is also provided with a number of apertures or openings, c', corresponding with the number and shape in the web of the rails, with which they register when the plate is in its proper Serial No. l.

position. The plates C C being in proper position against the webs of the rails, and the apertures of said rails and plates V'coinciding, the bolts B are then passed through the rails and plates, and the nuts or taps b screwed thereon tightly against the louter face of the fish-plate G, the head of said bolt fitting against the outer face of the plate C, as clearly shown.

D designates a securing or fastening plate of rectangular form, and having apertures or 'openings d d therein, through which the outer ends of the bolts B pass, said plate iitting closely against the outer face of the fish-plate C. The apertures or openings in said plate D correspond in number with the bolts employed, and on the inner face the plate is provided with a series of countersinks, d d', surrounding the openings or apertures, of a shape and size corresponding to the nuts b,

which are adapted to iit snugly and securely therein and .be prevented from turning or becoming displaced thereby.

The ends of the bolts B are screw-thread ed, as at b3, and extend clear throughthe securing-plate and project slightly beyond the saine, and at their outer ends they are provided with openings or apertures b2, formed therein, through each of which is passed the arms of a fastening-key, E. The key E comprises a head, c, and two spring-arms, c, which spread or spring apart at their lower ends when in position in the bolt, and are thus prevented from being displaced, said key bearing against the face of the plate and serving to retain it in position and from becoming misplaced.

I have shownY but four bolts and their nuts and keys, two being arranged on each side of the line where the rails meet; but it is obvious that the number may be varied, and other details in construction may be made without departing from the principle or sacriiicing the advantages of my invention, the essential features of which will be readily understood from the foregoing description, taken in connection with the drawings.

It will be observed that the nuts b are housed within, wholly or partially, the securing-plate D, and areothereby shielded from the action of the weather, and, further, that IOO they are preventedfrom turning or becoming detached by the jars and shocks :incident to the passing of a train over the rail.

Ajoint constructed in acoordancewith my invention is cheap, simple, and strong and efficient in service, and may be readily detached from and applied to an ordinary railway-track.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a rail-joint, the combination, with the rails A A, of the apertured fish-plates C C, adapted to overlap said rails, a securing-plate, D,having openings d and countersunk portions d on its inner surface, bolts B, passing through fish and securing plates and the rails, nuts b, fitted on said bolts and housed within the countersunk portion of the plate D, and Y spring fastening keys E, passing through 2o an opening in each bolt and bearing against the face of the plate l), all arranged and adapted to serve. substantially as and for the purpose herein described.

In testimony that I claim the foregoing as 25 my own I have hereto afxed my signature in presence of two witnesses.
